Orisil

Orisil is amorphous fumed silica produced by vapor phase hydrolysis of silicon tetrachloride in flame of hydrogen and oxygen, the resulting product is pure x-ray amorphous silicon dioxide (SiO2) The B.E.T. Surface Area is the quantitative characteristic that defines the different grades of Orisil.

Grades

Orisil is a pure amorphous pyrogenic silica. The appearance of the material is a fine, bluish-white powder. This form of silica is non-toxic and is not flammable or combustible. The range of Orisil products consist of the following grades: Orisil 200, Orisil 300, Orisil 380- hydrophilic, Orisil M130, Orisil M200, Orisil M300-hydrophobic.
